Uva-Cão

Found exclusively in the old vineyards of Serra da Estrela, and famous for its high levels of acidity, this variety was usually planted at the entrance of the vineyards - definitely not the best grape to eat. The name says it all: Uva-Cão ("Dog-Grape"), "the grape that guards the vine." To the most curious and the most sensitive, a warning - the acidity of this wine is remarkable!
